Question

Truth table for the given circuit is

Answer 1

(B) is the correct option

Answer 2

Answer:

Table B

Explanation:

As per the truth table

C=A.B and D=A¯.B  and

E=C+D=(A.B)+(A¯.B)

Thus, the truth table will be -

A - 0 0 1 1

B - 0 1 0 1

A - 1 1 0 0

C=A.B = 0 0 0 1

D=A.B = 0 1 0 0

E = 0 1 0 1

Since, C=AB  and D=A'B

E=C+D=AB+A'B=B(A+A')=B

So the output will be same as table B.
